Li-Fi Sector: Growth Drivers and Challenges

Growth Drivers

• Rising adoption in healthcare facilities: Hospitals are highly adopting Li-Fi for safe and interference-free communication in highly sensitive clinical environments where radio waves are limited. Traditional wireless systems such as Wi-Fi often pose risks near medical imaging equipment such as MRI and CT scanners due to electromagnetic interference (EMI), which can affect both equipment performance and patient safety. Li-Fi mitigates this risk by using light waves for data transmission, offering high-speed up to 224 Gbps, localized, and EMI-free communication which are ideal for hospital sensitive surroundings.
   
• Government-led smart infrastructure initiatives: Governments globally are combining Li-Fi into smart city projects to enable real-time data transmission in street lighting and traffic systems, improving urban safety, energy efficiency, and traffic management. In 2023, the Indian Ministry of Electronics and Information Technology (MeitY) started a pilot project under the National Smart Cities Mission, using Li-Fi-enabled smart streetlights in a few parts of Pune and Bhopal. This initiative was targeted to reduce latency in traffic tracking systems and support public safety communication. The pilot project brought a 15% improvement in traffic flow analytics and enhanced security across the pilot zones. Li-Fi-enabled smart lighting systems can transmit location-specific data to citizens, such as emergency alerts or public transport schedules, while also serving as secure access points for municipal networks.
   
• Growing investment in R&D by market leaders: Significant R&D investments are encouraging innovation and commercial readiness for entering the Li-Fi market. Top market leaders and startups are developing next-generation Li-Fi chips, routers, and integrated systems for expanding beyond niche environments into broader consumer electronics, automotive, and industrial applications. These investments are targeted at increasing transmission range, lowering costs, and integrating Li-Fi into 5G and 6G hybrid networks. Government grants and innovation funds are further encouraging this demand. In 2024, pureLiFi, a Scotland-based pioneer in Li-Fi technology, secured $18 million from the Scottish National Investment Bank to scale its Li-Fi chip production. These chips are being prepared for use in smartphones and AR devices via partnerships with leading OEMs. The investment is expected to increase production capacity by 250% by 2026, positioning pureLiFi as a central player in making Li-Fi commercially viable to global markets.

Major Technological Innovations in the Market

The global Li-Fi market is rapidly expanding, fueled by tech innovation and cross-industry demand. Li-Fi integration with smart lighting and IoT enhances secure, high-speed data transfer, especially in enclosed spaces. Around 60% of schools in advanced regions have adopted it, while the automotive sector is set to reach 45% adoption for V2V and V2I communication by 2030. In healthcare, about 55% of hospitals in developed countries are using or piloting Li-Fi for EMI-free device communication. Retail adoption is also rising, with 40% of smart stores using Li-Fi for indoor navigation and personalized marketing.

Integration of AI and ML in the Market

Artificial intelligence and machine learning are transforming the Li-Fi industry by streamlining product development and boosting operational efficiency. Businesses are using AI-based simulations to accelerate design cycles, cutting both development time and costs. This integration is improving not just productivity but also the quality and customization of Li-Fi solutions, leading to greater customer satisfaction. As AI and ML technologies advance, their role in driving innovation and optimizing performance across the Li-Fi market is expected to grow significantly.

Challenges

• Limited infrastructure compatibility: One of the key challenges faced by the Li-Fi market is its limited compatibility with existing communication infrastructure. Unlike Wi-Fi, which relies on widespread radio frequency (RF) systems, Li-Fi requires specialized light-based transmitters and receivers, such as LED bulbs and photodetectors. This necessitates significant upfront investments in retrofitting or replacing current networking systems across buildings, factories, and public infrastructure. Li-Fi cannot penetrate walls or work efficiently in direct sunlight, which restricts its deployment to confined and controlled indoor environments. According to data from the U.S. Department of Energy, retrofitting commercial buildings with advanced LED systems can cost between $2 to $6 per square foot, which poses a cost barrier, especially for small and medium enterprises (SMEs). Furthermore, the absence of standardized global protocols delays integration across industries and regions. Until universally adopted standards are established, such as those by the IEEE 802.11bb Task Group, Li-Fi adoption will remain restricted to pilot programs and niche use cases.
